GAS-LAMP.

. Specification of Letters Patent.

Patented July 2, 1216..

Application filed November 8, 1915. Serial No. 60,292.

To all whom it may concern:

Be it known that l, l-lUs'roN H. MAnns, a citizen of the UnitedStates, and a resident of the city and county of Denver, State of Colorado, have invented certain new andconsumption of the same. I

Another object of the invention is to providev a lamp of this class for effectively generating gas from hydrocarbon fuel and for creating a combustion of the gas sufficient for illuminating purposes.

Another object of the invention is to providea lamp of this class, in connection with which gasolene, or any other hydrocarbon fuel may be employed with complete safety from explosions, or escape of the fuel.

Another object of the invention is to provide means for automatically shutting off the. supply of fuel in the event that the combustion is accidentally, or otherwise discontinued.

With these and other objects in view, the invention will be described with reference to the accompanying drawing, forming a part hereof.

In this drawing, Figure 1 is an elevation view of the lamp; Fig. 2 is a longitudinal sectional view of the needle feed valve; Fig. 3 is asectional view of the lower portion of the lamp; Fig. 4 is a sectional view of the.

supply valve; and Fig. 5 is a detail view of a thermostatic control for the supply valve.

Corresponding andlike parts are referred to in the following description and indicated in all the views of the accompanying drawing by the same reference characters.

The numeral 5 designates a hollow pipe, bent downwardly at its upper extremity, as shown at 6. The extremity of this bent por tion 6 constitutes the discharge extremity for the gas, the gas being consumed as it is emitted from this extremity. A cap 7 is threaded on said discharge extremity, said cap being provided with a mantle screen 8, through which the gas passes. A. carbon retaining receptacle 9 is connected with the induction extremity of the tube 5 by means of an arm 10, having a longitudinal slot 12 therein, which receives a bolt 13, mounted on the tube 5. This bolt 18 is provided with a nut 14, which, when tightened, engages the arm 10 and holds the latter fixedly with the tube 5. The tubeo is also provided with an upper arm 16, integrally formed with said tube, and provided with a vertical slot 17 therein, which receives an adjusting bolt 18 of a collar 19. This collar 19 receives the housing 20 of a needle feed valve and supports the said needle feed valve on the arm 16. The needle valve housing 20 is provided with a longitudinal opening 21 therethrough in which a needle valve piece 22 is threaded. One extremity of the housing 20 is provided with a packing cap 23 threaded thereon, while the opposite extremity of said housing is provided with a cap 24 threaded thereon, said cap 2 f having a chamber 25 therein adjacent the discharge extremity of the opening 21. This chamber 25'is con nected by means of arelatively small pipe 26 with the carbon retaining receptacle 9,

the said tube 26 being disposed in close proximity to thedischarge extremity of the tube 5, whereby the resulting heat from the combustion of the gas causes the hydrocarbon to vaporize as it flows through the said pipe 26. A supply pipe 27 is connected with the needle valve housing 20 and discharges into an enlarged portion-28 of the opening 21.. Thesupply of the hydrocarbonis con trolled by the needle valve 22 for regulating its passage through the pipe 26. The volatilized fuel passes from the pipe 26 into the carbon retaining receptacle 9 and thence through a discharge jet 29 of said receptacle into the lower extremity'of the tube 5. The

' jet 29 is formed through a nipple 30,.which is disposed in alinement with the lower extremity of the tube 5, and separated from the latter forming a gap in which a suflicient quantity of air is mixed with the fuel before the fuelis passed into the tube 5. This gap may be widened or shortened, as desired, for regulating the mixture of air, by changing the position of the tube 5 in a vertical direction. This adjustment is accomplished by means of the attachment of the carbon retaining receptacle 9 with the tube 5, heretofore described. When such adjustment is made, it will of course be neclilo essary to also change the altitude position is made for this adjustment of the housing 20 simultaneously with the adjustment of the position of the said receptacle 9, by means of the slotted arm 16 and the adjusting bolt 18, heretofore described. A plug 31 is threaded in the bottom of the carbon retaining receptacle 9, as shown at 32, by the removal of which, access may be had to the interior of the said carbon retaining receptacle for placing oil therein, or for cleaning the said receptacle. This plug 31 1s provided with a nipple 33 thereon, and through which a needle valve 34 is threaded, the point of said needle valve 34 adapted to be seated in the jet 29. The jet 29 is of conical shape, whereby adjustment of the needle valvein said jet will control the escape of gas through said jet. A quantity of oil is adapted to be retained in the carbon retaining receptacle 9, and in which oil, the carbon is collected from the fuel as the latter passes through said receptacle, thereby preventing the circulating channels of the lamp from becoming clogged with carbon.

A supply valve 35 is located in the supply pipe '27, said supply valve being automatically controlled by means of a thermostat 36. A bell-crank lever 37 is connected with the valve piece of the valve 35, and with one extremity of said bell-crank lever 37, a rod 38 is connected, the lower extremity of the said rod 38 being connected with thermostatic plates 39. An arm 40 extends from the supply pipe 27 and is engaged by said thermostatic plates 39. Now, therefore, when the combustion of the gas is discontinued,

whether accidentally or intentionally, the

while its other extremity is free. The thermostat bar 41 is composed of two strips of metal having different degrees of expansion under the same temperature, and so positioned that one of said strips of metal will contract under a'lowering temperature to move the thermostat bar outwardly, as rep' resented by dotted lines. The supply valve 35 is provided with a valve piece 43, having an arm 44 connected with its outer extremity and. a weight '45 suspended from said arm. The arm 441is provided with an extension 46, formed by bending the said arm 44, as shown. at 47. A screw 48 is positioned in the bend 47"and is extended from the latter and is adapted to be engaged by the upper extremity of the thermostat-bar 41 for holding-thevalve piece 43 in-the open position.

This position is represented by the full lines in F ig. 5, and its closed position represented by the dotted lines. The valve 43 is threaded in the coupling 49, as shown at 50, whereby, when the arm 44 is turned in an arc, the valve 43 is actuated either inwardly or outwardly, as the case may be. To open the supply valve, the arm 44 is raised to the full line position, and the screw 48 engaged with the upper extremity of said thermostat bar 41, which normally occupies a position in the path of the said screw 48, thereby holding the valve in the open position. Now, in' case the lamp is extinguished, the temperature in the vicinity of the thermostat bar 41 will be lowered, causing the said bar to move to the dotted line position represented in Fig. 5 and to disengage the screw 48, whereby the weight 45 will actuate the arm 44 to the dotted line position and close the supply valve, the extension 46 of the arm 44 engaging the upper extremity of the thermostat bar 41 for limiting the movement of the said arm 44.

It will be understood that any form of thermostatic control may be employed by the provision of suitable means of application, and, therefore, I am not limited to the forms shown, these forms being shown because of the fact that they have been specially designed to meet the requirements of the use to which I put them.

The use of the thermostatic control is not confined to application to gas generating apparatus of the class described in this specification, but may be applied to the gas pipes used for supplying gas to a jet of ordinary construction and use. This thermostatic control will be found of especial advantage when gasolene, or other highly combustible fuels are employed.

l/Vhile I have described and illustrated herein a specific form of the invention, it is understood-that I am not limited thereto and that the same may be modified and varied without departing fromthe spirit of the invention or the scope of the appended claims.

Having thus described my invention, what I claim and desire to secure by Letters Patent 1s:
